Wiresheet: Ctrl+click to select several links, delete them together

Browse Source 
Ctrl+click toggles a link in the selection; Del or the link popup deletes
every selected link after one confirmation, as a single undoable step.
On a device, links the device refuses stay and are named in one warning.
